Change Adjusted Date & Time of Photo in Photo Application

I have beat my brain attempting to write a Applescript that will change the Adjusted Date & Time of selected photos in the Photo Application. While I can easily set the date, for example 04/03/2003, I have been unable to get this date (or any date) to be accepted by the Photo Application as an Adjusted Date. The errors returned are numerous depending on whatever I do to push the desired date.

So my question is, is it even possible to write an Applescript that will push a new Adjusted Date (& Time) for a given photo into the Photo Application.
